JORC Resource
The deposit hosts an independent JORC (2012) Mineral Resource Estimate of 10Mt @ 1.20% Li2O (0.33% cut-off) across three (3) spodumene bearing pegmatite dykes. All pegmatite dykes remain open along strike with potential for significant resource growth.
It is an exceptionally high-quality and robust Mineral Resource Estimate:
- 62% within the Measured and Indicated categories
- 88% (~8.85Mt) averages 1.3% Li2O
- 76% (~7.64Mt) averages above 1.4% Li2O
- 66% (~6.56Mt) averages above 1.5% Li2O
A breakdown of the Mineral Resource Estimate, which incorporates 174 diamond core drill holes for over 35,000 metres of drilling is as follows:

The current Mineral Resource Estimate will be used to support feasibility studies where the Company is hoping to achieve a base-case that comprises of a low-CAPEX circa 180Ktpa operation producing a clean SC6 product (6% Li2O spodumene concentrate) for domestic and/or global markets. The first stage in this regard will be the commissioning of a Preliminary Economic Assessment/Scoping Study. If further exploration success and an increase in mineral resources is achieved, expanded production scenarios will be assessed.
